This is the procedure is loosely inspired from Naoki Hamada to install 4.0 BSD onto SIMH's VAX 11/780 emulator. I can't get the standalone programs to run on SIMH, so instead I'm using the 4.0 standalone to bootstrap 4.1. So the ini files, and initial disk prep is the same.

Booting from disk

This part relies on you having extracted the 4.0 BSD boot program, as there is no console floppy in SIMH. Or I haven't figured out how to create one, so it is injected into memory and executed. Load the simulator as follows and it'll boot up to the login prompt.
